Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
Consult shown in Fig. 1 and Fig. 2, plastic injection mould of the present utility model, be applied to the plastic injection mould imbedding ejection formation, it mainly comprises die holder 2 two parts in an outer mould base 1 and, wherein: this outer mould base 1 preferred embodiment comprise one first outer mould base 11 and one second outer mould base 12 the formation that is involutory, the inside of this outer mould base 1 provides this interior die holder 2 assembling bearing; This first outer mould base 11 is provided with the runner 112 that more than one geat 111 and more than are communicated with this geat 111, be equiped with an electric heating unit 113 in this runner 112 and be used for heating of plastic to maintain the temperature of high temperature plastics, the high temperature plastics poured into from this geat 111 can not be solidified (i.e. so-called hot runner device).Consult shown in Fig. 3 and Fig. 4, this interior die holder 2 preferred embodiment to comprise in one first in die holder 21,1 second die holder 23 in die holder 22 and the 3rd; This is provided with at least one die cavity 221 in die holder 22 in second, and have more than one locating piece 222,222 ' in this die cavity 221, this locating piece 222,222 ' penetrates part 3 in this die cavity 221, to carry out imbedding ejection formation for locating more than one burying; And this in first in die holder 21 and the 3rd die holder 23 be covered on die cavity 221 both sides of this die holder 22 in second, and then this die cavity 221 to be closed.
Because mould of plastics of the present utility model is for vertical type plastics ejection machine institute, consult again shown in Fig. 3, Fig. 4 and Fig. 5, above-mentioned this in first die holder 21 be incorporated in this first outer mould base 11 of mould upper end, according to the structure demand of ejection formation, this in first die holder 21 internal shaping have first die cavity 211 that should bury for a pair and penetrate part 3 first end, make this first die cavity 211 be communicated to this runner 112.Above-mentioned this in second in die holder 22 and the 3rd die holder 23 be then that group is tied in the second outer mould base 12 of mould lower end, according to the structure demand of ejection formation, in the 3rd, die holder 23 internal shaping has second die cavity 231 that should bury for a pair and penetrate part 3 second end.This locating piece 222 above-mentioned, 222 ' to be fixed in the 3rd on die holder 23, when this is in second in die holder 22 and the 3rd during die holder 23 groups knot, this locating piece 222, 222 ' is convexly extend in the die cavity 221 of this die holder 22 in second, utilize this locating piece 222, 222 ' will bury and penetrate part 3 and be positioned in die cavity 221 and can not produce skew, this locating piece 222 simultaneously, 222 ' and this bury and penetrate part 3 and also provide plastics material closed moulding in this first die cavity 211 above-mentioned, in this second die cavity 231 and this die cavity 221 the shaping position 221a that selectes, guarantee that this buries and penetrate the relative accuracy of part 3 after imbedding ejection formation and between plastic construction.
Plastic injection mould of the present utility model, particularly be applied in rule veriform linear slide block bury penetrate part 3 implement imbed ejection formation engineering method, part 3 is penetrated in external form part because this of linear slide block buries, just like general shown in Fig. 6 A ~ Fig. 6 D and Fig. 7 A ~ Fig. 7 D, there is multiple different external structure and size A ~ F, various bury penetrate part 3 only within it recess 31 (part for the assembly of line rail) be the same structure and size (as in Fig. 6 A ~ Fig. 6 D with the scope that dotted line institute frame selects), therefore the utility model utilizes the architectural feature on this product, this is buried and penetrates part 3 with this inner fovea part 31 and a top end face 32 and this locating piece 222 above-mentioned, 222 ' mutual contact is to obtain supporting and location.
And, as can be seen from figures 8 and 9, from this first outer mould base 11 above-mentioned runner 112 pour into plastics material, be subject to after mold closing simultaneously this bury and penetrate part 3 and this locating piece 222,222 ' retrains jointly, make plastics material can not in other spaces 221b of die cavity 221 beyond channelling to this first die cavity 211 above-mentioned, this second die cavity 231 and this shaping position 221a, guarantee that plastics material only can bury in this chosen place (being namely molded over this in the present embodiment to bury in two ends and this inner fovea part 31 penetrating part 3) penetrating part 3 by forming covered, this is buried to penetrate part 3 Overmolded.
For another example shown in Fig. 3, Fig. 4 and Fig. 5, above-mentioned this locating piece 222,222 ' concrete comprise more than one and buries the first locating piece 222 of the inner fovea part 31 penetrating part 3 for contact at this, and more than one bury the second locating piece 222 ' of the top end face 32 penetrating part 3 for contact at this, be positioned at the structure of inner fovea part 31 whereby by this first locating piece 222, make plastics material only can bury in two ends and this inner fovea part 31 penetrating part 3 in this by forming covered; And bury the second locating piece 222 ' of the top end face 32 penetrating part 3 for contact at this, its gauge can bury according to above-mentioned this size A, B, C (as shown in Fig. 6 A ~ Fig. 6 D) etc. of penetrating part 3 and be embodied as polylith, therefore, it is possible to bury the pattern of penetrating part 3 replace according to this.
Due to the utility model can be applicable to above-mentioned with rule veriform linear slide block multiple bury penetrate part 3 implement imbed ejection formation engineering method, therefore, die cavity 221 spatial design of this die holder 22 in second of the utility model, design with the overall dimensions greatest common divisor of linear slide block, all burying with the veriform linear slide block of rule is made to penetrate part 3 and all can be suitable for (in the lump as can be seen from figures 8 and 9), the die cost of product development is made to be down to whereby minimum, and then obtain best economic benefit, the competitiveness of improving product in price.
Again as shown in Figures 4 and 5, above-mentioned this in second die cavity 221 number of die holder 22 be preferably embodied as two caves, this is the setting considering hot runner device and die holder circulating cooling water channel, therefore adopt two patterns relatively leaned against to arrange die cavity 221, make melt and dissolved plastics inject penetrating pressure and this can not be buried and penetrate part 3 and push displacement in mould, can stablize and keep burying penetrating part 3 and the relevant physical dimension after plastics forming.
The above embodiment is only for absolutely proving the preferred embodiment that the utility model is lifted, and protection domain of the present utility model is not limited thereto.The equivalent alternative or conversion that those skilled in the art do on the utility model basis, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
